1: You counted down the days to the release of The Last Jedi.
2: You get totally bummed out when the movie ends because you have to wait two years to find out what happens next.
3: You know the names of a bunch of Star Wars (and Harry Potter) actors. (Sure, you know who was Luke Skywalker, but who was Rey? Kylo Ren? Finn?...well, you get the idea.)
4: You get excited to find out that a Star Wars/Harry Potter actor/actress will be in some other movie, even if you don't plan to see that movie. Eddie Redmayne (Fantastic Beasts' Newt Scamander) is in some stop-motion kid's movie that's coming out soon (he really is, by the way) , and you think that's cool.
5: You dream of getting the autograph of some awesome actor (Harrison Ford for me).
6: You/someone who looks up to you says that their favorite superhero is Rey.
7: You're so upset that you've already read the Harry Potter series (what will you read now?)
8: You thought that the Star Wars prequel trilogy/Indiana Jones and the Kingdom of the Crystal Skull was actually at least halfway decent.
9: You freak out when you hear they're building a Star Wars-themed hotel, or that they've created a Star Wars virtual reality experience.
10: You're constantly referencing Star Wars/Star Trek/Harry Potter/Lord of the Rings/Indiana Jones/whatever your movie or book obsession is (everybody has at least one!)
